Edulcorante na Água de Consumo e Efeitos Sobre o Desempenho e o Desenvolvimento da Mucosa Intestinal de Leitões Submetidos ao Desmame Precoce Segregado

Abstract

An experiment was conducted with the objective to evaluate the effects of the induction of the drinking water with sweetener consumption in the nursery phase (10th to 30th day of age), on the performance of 270 piglets (male and females) submitted to segregated early weaned and its residual effects on their pre nursery (30th to 45th day) and nursery phases (45th to 62nd day) were evaluated. A completely randomized design in a 3 x 2 factorial arrangement with three treatments with two sexes and three replications were used from 10 to 30 days of age of the piglets. The treatment were: T1 - drinking water without sweetener; T2 - drinking water with sweetener and T3 - drinking water with and without sweetener simultaneously offered. Average daily gain, daily feed intake and feed: gain was recorded at 30th, 45th and 62nd days. Daily drinking water consumption was recorded only from the 10th to 30th day. Six piglets per treatment were slaughtered at the 22nd day and a medium part of the duodenum and jejunum samples were collected to measure villi height and crypt depth. Diarrhea incidence was observed up to 10 days after weaning. It was not observed differences for the studied variables, except for average daily gain and daily feed intake from 30th to 45th and 45th to 62nd days phases and for average daily gain from 10th to 62nd days that favored the female piglets. The use of drinking water with sweetener did not affect the water consumption, the piglet performance and the mucosa intestinal quality.
